Hallo, gentlemen,   Is there any information about when the Germans started stenciling "Keine Bombe" ("Not a bomb") in their drop tanks? Obviously when air war started to occur over Germany in earnest, but I am building some models which would cover the critical period, that is, second half 1943, and some precision would be useful. Also, if there was some difference to be made according to the theater of operations (MTO or Ostfront later than Home?)   Thank you for your atten
